Hi Christian - Normally, you should be able to restart the computation
with "getdp -restart".

But it would be nice to know why the memory fills up over time: do you
by any chance ask for post-processing operations at the same time as the
resolution ("getdp -solve -pos")? This is actually not a good idea for
long time-stepping computations, as GetDP then stores all the solutions
during the resolution in order to have them available for the
post-processing stage. For long time-stepping computations it is best to
do both steps separately ("getdp -solve", then "getdp -pos"): this way
GetDP can free the solutions as soon as it does not need them anymore,
and the post-processing step will simply re-read the solutions from disk
later on.

Hope this helps,

Christophe
